I broke my banner!

I realized I should probably put some kinda CotY badge on my site. I added it to my main banner and uploaded it over the old one; there were no errors and it said it uploaded successfully, but now there's just a blank field where my banner should be.

Am I just being impatient? Does it take some time to appear for some reason? Or did I make the file size too big now? (It's still only 463K, so I doubt it.) The image is the exact same size (994x199 pixels) as it originally was.

It's still wonky for me. I even cleared my cache and tried viewing it in Internet Explorer, but it's just not there. I've tried saving it as both a JPG and a PNG. I tried KillerVP's suggestion and deleted the banner, then re-uploaded. None of these have worked.

When I attempt to upload a new banner, I can select it and see the small preview, but as soon as I click Save it vanishes.

My banner IS there, but for some bizarre reason I can't view it on my work PC. I tried it in Chrome, IE, and Edge and it's just not there. But if viewed from a different device, the banner is right there.

There have been any such changes that I'm aware of, but I can ask if anything has changed. That being said, the fact that I see the banner just fine and UTM doesn't see it (or any banners for that matter) would seem to imply that it's some sort of display issue on UTM's end.
